No, Heroin is derived from opium coming form the poppy. Cocaine comes from the coca leaf.
Either heroin, or cocaine.
Let me start by stating that I assume you meant "heroin". Anyway, no, the chemical structures of these compounds are completely different. Heroin is derived from morphine whereas cocaine is a tropane alkaloid. Thus, it is not possible to convert cocaine to heroin.

Heroin.
Both cocaine and heroin will effect your concentration. You do not want to take these substances and then get behind a wheel.
it was cocaine because if you actually remember the seen where she overdoses you'll see that she is sniffing :D that's wrong, its heroin. you can sniff heroin just like cocaine. Heroin is not allways brown, it can be white and it looks just like cocaine. http://upload.wikimedia.org/wikipedia/commons/5/5bHeroin_asian.jpg also, she had been doing cocaine all night and she snorted the equivalent of what she had been snorting in heroin, so she ods. Two extreme opposites mixing at high doses can be fatal.
Cocaine and heroin are two totally different chemicals, and require totally different tests be applied. For dip-stick testing you need a stick for cocaine and another for heroin; assay testing requires two different programs in your machine.Given that, if you're running SAMSHA-5 drug tests by either methodology, you'll have both a cocaine test and a heroin test.
